I was wondering if there's still any interest in people wanting to buy Original stage 2 heads? Also, who is the authority or go-to guy for information on these rare heads? Thanks In advance for any info.
I’m sure this was discussed in the past here on the board. I have a set of iron stage twos that would’ve been released by Buick in 1972 I do believe they originally listed at $215 a piece bear.
They were the hot ticket to go fast in the mid to late 80s with a Buick 455 before TA started reproducing them.
Buick made very few sets of S2 heads, something like <75, and probably 10/30% are still out there. But that's just a guess... There was a guy in CA awhile ago that was asking $25K for a set. Not sure if they were sold or not.
Price seems high were they NOS still in boxes ? What about the Kustom headers were they available with the heads ?
I sold a set in the 90s for $2500, about 8 years ago another set for $6500. The last set I have I've been offered $9000. I also still have a set of custom headers. The iron stage 2s and headers were on Thumper for years.
I was offered 10 K for mine couple years ago that was with the polish KB rocker covers an Kustom headers.
People interested in the Stage 2 part (in my opinion) are not using them for racing . I think it would be more for show or just " I have a set of STAGE 2 Iron heads " The heads would be more like double Gary's last offer and the B4B intake , holley 4187 , pistons ,headers and cam ???????????????????

Then Dennis Manor got a hell of a deal on the stage 3 4 bolt main block and tunnel port heads One off tunnel ram intake. It was for sale for 18 K.
Its really amazing how well the iron stage2s ran. I ran Thumper in the early 80's with irons and ran consistent 10.4s. All old school. 464 ci, KB mark IV hyd cam, 12 to 1 compression, B4B, TQ1000, 69 rocker arms, 4.30 gears and 4000 converter, no girdle, al. rods,lightweight Venolia pistons. Ran a best in good air at Norwalk of 10.28. Here we are today, with all good parts and technology and thousands of dollars and we've picked up 1 second?
When I bought my stage 1 in 83 it was running the original window rattler KB 70S1 Motor ended up with a rod knock. Motor ate the front Cam bearing With the Kenne Bell double gear oil pump. Rebuilt the motor in 85 using the later version 473 lift C107 was just a kid installed it straight up never degreed. Car went a consistent 1260s at 106 mph shifting at six grand if I shifted it to 5800 it probably would’ve been quicker. I started having valve train issues so I installed the iron stage 2 heads no other changes it ran 11:84 at 111.50 mph. End of valve training problems.
I bought another 1000 TQ and strip kit off a board member from Texas he said it used to be on your race car thumper.
I think it would be great on a 350, bet it wouldn't have a problem like the Q-Jet with the SP3 intake.
I don't, I use a 750 dbl pump Holley but there was a couple people here that had problems with bogging off line and just could not get the carb to work well with the SP3.
